Definitions

  • SLT family Additional members of the SLT family have subsequently been isolated that can be distinguished serologically, on the basis of gene sequence or host specificity (Gannon, V.P.J., et al., J Gen Microbiol (1990) 136 :1125-1135; Weinstein, D.L., et al., J Bacteriol (1988) 170 :4223-4230; Ito, H., et al., Microb Pathog (1990) 8 :47-60; Head, S.C., et al., FEMS Microbiol Lett (1988) 51 :211-216; Schmitt, C.K., et al., Infect Immun (1991) 59 :1065-1073; Scotland, S.M., et al.
  • SYNSORBTM bearing haptens e.g., the G M1 ganglioside Neu5Ac(2-3) ⁇ Gal(1-4) ⁇ Glc and heat labile toxin from enterotoxigenic E. coli would be expected to behave similarly.
  • a single SYNSORBTM bearing several haptens with specificity for the different binding subunits of several different gastrointestinal infections should now be possible.
  • Such universal SYNSORBTMs would provide rapid, simple simultaneous diagnosis of a variety of gastrointestinal disorders.
  • the effect of the compositions of the invention in neutralizing SLTs can be measured by comparing activity of SLT with and without treatment with the compositions.
  • Activity of the SLTs can be assayed by taking advantage of the toxicity of these compounds to Vero cells.
  • Vero cells ATCC CCL81
  • Vero cells ATCC CCL81
  • MEM minimal essential medium with Earl's salts
  • FBS fetal bovine serum
  • the composition may comprise the ⁇ Gal (1-4) ⁇ Gal (1-4) ⁇ GlcNAc subunit or ⁇ Gal (1-4) ⁇ Gal (1-4) ⁇ Glc subunit.
  • the said subunit may be coupled to a pharmaceutically acceptable support which may comprise a matrix.
  • the subunit may be coupled to said pharmaceutically acceptable support through a spacer arm which may correspond to MCO.
